Item 6 for what value of a is 8x−8+3ax=5ax−2a an identity?

Let's rewrite the expression as

So, if , you may divide both sides by , the equation becomes , and the only solution is , which means that this is not an identity (an indentity is tautologically true, no matter the value of x).

If instead , you are multiplying both sides by zero, so the equation becomes

So, it doesn't matter which value for x you choose, because you will always end up with , which is obviously always true.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
